Too many middle school students struggle to comprehend their textbooks in science and other content areas. Thus, many adolescent learners lag behind in developing scientific literacy, which the National Research Council has defined as sufficient understanding of the scientific concepts and processes required for personal decision making,…

Tomlinson and Germundson compare teaching well to playing jazz well. Excellent teaching involves a blend of techniques and theory; expressiveness; syncopation; call and response, and, frequently, improvisation. Weaving in analogies to jazz, the authors delineate four elements of such teaching: curriculum that helps students connect to big ideas,…
